Connect motor wiring#
How to connect the motor wiring!
depends on the type of motor:#
- Read step 4A for a 230V motor.#
- Read step 4B for a 12-24V motor. !
- Read step 4C for a motor with a momentary switch.!
!
!
!
4A. !
Connect 230V motor#
(1) Connect the (blue) neutral wire from the!
motor to the [N] contact. (2) Use a seperate piece of wire to connect
[L] with [COM]. (3) Connect the live wires from the motor (brown and
black) to the left and right [ ] contact. These positions can be
interchanged to reverse the up and down motion of the motor.!
!
!
!
!
4B. !
Connect 12-24V motor#
(1) Connect the 24V+ wire to [COM].!
(2) Connect switch wires A+ and B+ to the left and right [ ] contact.
These positions can be interchanged to reverse the up and down
motion of the motor. Never connect 230VAC wires to low-voltage
wires.!
!
!
!
!
4C. !
Motor with momentary switch#
The motor only has 2 wires. (1) Connect one wire to [ ] and the other
wire to [COM].!
These positions can be interchanged to reverse the up and down
motion of the motor. (2) Use a seperate piece of wire to connect both#
[ ] contacts. Never connect 230VAC wires to low-voltage wires.!
